Developing pattern and more frequent snow could keep cold air in place

Tom SkillingCHICAGO TRIBUNE

The pattern of frequent snowfall (15 measurable snows so far this winter versus three last year by this time) continues with a dusting this afternoon and potentially more snow Sunday night/Monday and Wednesday night/ Thursday. The reflective snowpack they produce will make it difficult for much recovery in the colder-than-normal temperature regime, suggesting cold will linger through at least next week.
